Keeping gravel free of weeds

Just got done with the twice annual roundup spraying on my 40 ft of gravel drive. I wonder if salt would not be a better alternative and more lasting?

I have used oil but don't want to go there......

Is is possible for the salt to end up washing into your lawn?
I think the magic of Roundup is that it's basically harmless after a certain amount of time in sunlight.
 
It's not bordered by a lawn so no big deal on that. Roundup if used frequently is rather resilient.

That garbage has never, ever worked for me.
 
Have you considered using a product with Roundup + a germination inhibitor? I use a spray called ProDeuce - it's Roundup + Prodamine. It will typically keep ground clear for a year if applied correctly.

The problem is that with time organic material such as decomposing leaves finds its way onto the top layer above the garden fabric and provides the nutrient base for weeds to take hold. Eventually you have to remove the gravel and weeds, replace the fabric, separate the nutrients from the gravel, and reapply the gravel.

I'm just saying that garden fabric is not as maintenance-free as people may think. I've seen many a landscaped bed covered with weeds, even though garden fabric was put down.
 
Traffic or keeps the weeds down abit. I've got a long driveway so I drive in and out on the edges which cuts the growth off mostly there. Round up is the most effective in an area through.
 
Glyphosate works well as a non-discriminate, post-emergent herbicide. Putting down a pre-emergent herbicide to control germination should extend the time between glyphosate applications.

Landscape fabric has it's fault, as mentioned above. It requires periodic maintenance.

Salt is great if you don't get a lot of rain, or/and the run-off won't damage grass or flower beds. I have used it on cracks in driveways in the past, and along decorative pavers. I don't use a lot of pre-emergent, but usually use Dithiopyr when I need something more than Atrazine, 2,4-D, or Penoxsulam.

They may not be available retail, but a local garden shop, or lawn chemical store, should be able to push you in the right direction if they aren't.
 
I use landscape cloth in double layers. Yes it needs maintenance. I don't use poisons for a number of reasons. Mostly the shallow well,
 
Regular unleaded gas works just as well without exposing yourself to the toxins, carcinogens and endocrine disruptors in Roundup, (nasty stuff). Perhaps diesel as well if you can get it without the red dye.

I spray just before sunset on a calm evening so it doesn't evaporate too quickly
 
Well don't drink/inhale/bathe in the round-up (or gasoline for that matter), follow the label to the T, and poof your body keeps functioning. Though I do agree, there are better options out there than glyphosate. That is, perhaps, why he was asking about the use of salt. Mostly not toxic.

I use the Salt Water from my Soft Water Tank on the weeds in the driveway and the gravel around the house. May have to apply it twice a year.
 
LOL - easy to pick out the certified applicator in these threads. Atrazine is an RUP.

It's also interesting that people assume that things they use daily are safer than pesticides. Gasoline was mentioned above: https://medlineplus.gov/ency/article/002806.htm
